心脏电生理检查的开展使临床医师不仅能明确认识室上性心动过速(简称室上速)的发生机理,定量分析传导组织的传导性和不应期,并可应用此技术对室上速进行治疗, 一、明确室上速的发生机理和类型 现认为室上速的发生机理有折返激动、自律性增加和触发活动等。 Cardiac electrophysiological examination to enable clinicians not only a clear understanding of the mechanism of supraventricular tachycardia (SVS), the quantitative analysis of conductive tissue conduction and refractory period, and can be applied to this technique on the supraventricular tachycardia For treatment, a clear mechanism and type of occurrence of supraventricular tachycardia now that the mechanism of occurrence of supraventricular tachycardia have rejuvenation, increased self-discipline and trigger activities.
